It can be done so in simple daily calculations such as calculating how much money you'll have after after you spend some.
<span>$100- $52= $48
and
if you switch it into an addition problem you will get
$100+(-52)= $48,
Or you can get $48 + $52 = $100</span>
4(x-3)-2+2x=5(3x-7)-9x
4x-12-r+2x=5(3x-7)-9
4x-12-r+2x=15x-35-9x
6x-12-r=15x-35-9x
6x-12-r=6x-35
add 12 to -35 which equals -23.
add 6x+6x it cancels out to 0.
-r=-23
to make r positive just add it -23
since 23 is already negative it would become a positive because a negative + negative= positive
answer: r=23
